Allied Nevada Gold Corp. (AMEX: ANV) low of $9.58. Announced a review of plans to complete an expansion Hycroft Mill Expansion by 2015. The company said, "Currently we believe there is value in phasing construction of the mill starting with a 75,000 tpd plant in 2015 and increasing to 130,000 tpd once the initial phase is operating according to plan. We expect that, once engineering is optimized, we will be able to show lower initial capital costs, initially processing only higher grade oxide and transition ore through the mill, leaching that ore on site and only producing sulfide concentrate as per demand. We are currently evaluating a number of options for onsite beneficiation of that concentrate."
